Switch tabs in Full Screen mode?

I just realized that while using Vivaldi in full screen mode I don't know how to switch to another tab without taking it out of full screen mode. Is there a way to do that, or do I have to continue doing as I've been doing?

If you activated the option "Switch Tab by Scrolling" (in settings-->tabs-->tab cycling) you can also keep the right mouse button pressed and scroll with the mouse wheel - just mentioning in case you are more a mouseperson than keyboard user.

Little sidenote about this option: This also activates tab switching when you are not in fullscreen and hover your mouse over a tab in the tabbar and scroll with your mousewheel. (Just wanted to let you know because this sometimes is filed as bug although it is intended to work this way)
